Update value in Angular Rich text editor component

19 Sep 20223 minutes to read

To achieve this, you need to bind the keydown event to the RTE content and capture the ctrl + s key press using its keyCode.
In the keydown event handler, the updateValue method is called to update the value property and then you can save the content in the required database using the same.

app.component.ts

import { Component, ViewChild } from '@angular/core';
import { ToolbarService, LinkService, ImageService, HtmlEditorService, RichTextEditorComponent } from '@syncfusion/ej2-angular-richtexteditor';
@Component({
  selector: 'app-root',
  template: `<ejs-richtexteditor id='defaultRTE' #sample [(value)]='value' (created)="onCreate($event)"></ejs-richtexteditor>`,
  providers: [ToolbarService, LinkService, ImageService, HtmlEditorService ]
})
export class AppComponent  {
@ViewChild('sample') public rteObj: RichTextEditorComponent;
public value: string = `
<p>The Rich Text Editor triggers events based on its actions. </p>
<p> The events can be used as an extension point to perform custom operations.</p>
<ul>
    <li>created - Triggers when the component is rendered.</li>
    <li>change - Triggers only when RTE is blurred and changes are done to the content.</li>
    <li>focus - Triggers when RTE is focused in.</li>
    <li>blur - Triggers when RTE is focused out.</li>
    <li>actionBegin - Triggers before command execution using toolbar items or executeCommand method.</li>
    <li>actionComplete - Triggers after command execution using toolbar items or executeCommand method.</li>
    <li>destroyed – Triggers when the component is destroyed.</li>
</ul>`;
onCreate() {
    const instance: any = this.rteObj;
    instance.contentModule.getDocument().addEventListener("keydown", function(e: any): void {
    if (e.key === 's' && e.ctrlKey === true) {
        e.preventDefault(); // to prevent default ctrl+s action
        instance.updateValue(); // to update the value after editing
        let value: any = instance.value; // you can get the RTE content to save in the desired database
    }
    });
    }
}
